Am I the only one who finds it a bit ridiculous that countless rap songs say far more deplorable things about black women, and yet they are praised and lauded?

They are not praised and lauded, they have been subject to criticism within the black community as well; the degrading portrayal of women and the rejection of it is why they don't run BET Uncut anymore. And profits for rap music have declined 20% this year off last year. The lyrics of rappers have always been criticized, but they're profitable because they appeal to young males.
